A chain cover 79 is provided on the rear arm 45. This chain cover 79 is used to cover the sprocket mounted on the engine output shaft. (Illustrated) and the chain 64 of the sprocket 63 of the rear wheel 7 has a bump. 1 Ding Qi said that the locomotive i has the structure described above. As described, the lower end of the main pipe P (^ ¾) and the rear end of each descending pipe i3b are connected to the cross pipe 16 for frame connection extending in the width direction of the vehicle body. The left and right rear stays 17 extending upward and rearward are respectively connected to both ends of the horizontal pipe 16. That is, as shown in FIG. 4, in the present embodiment, the lower end of the main pipe 12 (the rear end 1 is not welded and connected to the left and right sides of the main body 12) is integrally connected to the middle of the transverse pipe 16 in the longitudinal direction of the vehicle body in the longitudinal direction of the vehicle.铡 The separate end of each down tube is printed by the consumer co-operative end of the Central Standards Bureau of the Ministry of Economic Affairs. At the same time, the two ends of the 诼 cross tube 16 are welded together at the same time. Parts, each of the downcomers 131) and each of the rear stays 17 are connected by fl.夂: Ϊi and from the center of the vehicle width direction to the left and right ends of the horizontal tube 16 :: degrees to an appropriate length, regardless of the position of the rear end of the descending tube, can be left and right side of the soap body in the body waste., Upper teeth Visibility universally freely fixed each pole 17 (210X 297 mm) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (8) 蝻 The end part, and each downcomer 13b is also not affected After each; support 17 limit, can be freely positioned and fixed midway in the width direction of the cross-body 16. In this way, as shown in FIG. 9, the exhaust pipe 61 and the muffler which are arranged near the connection portion of each of the downcomers 13b and each of the rear stays 17 can be freely arranged without being hindered by each of the downcomers 13b and each of the rear stays 17. 62. Other parts such as chain 64, side bracket 67, etc. can enrich the functions of other parts and increase the freedom of locomotive design. In the above, the frame structure of the locomotive of the present invention has been described based on the actual shape of the semi-double turret-type body frame 10 which does not branch halfway as one main pipe 12; The locomotive of the branched semi-double-gun-type body frame or the double-piston-type body frame is also applicable, and is not limited to the above-mentioned embodiment. [Effects of the Invention] According to the frame structure of the locomotive of the present invention as described above, since the connecting portions' of the downcomer and the rear stay are not restricted to each other, each lower tube and each can be freely positioned and fixed in the vehicle width direction. Rear support bar, so it can be freely arranged without the interference of each lower tube and each rear support bar. The components near the connecting part can be arranged freely, and the parts near the connecting part can enrich the function of the part and make the locomotive Increased freedom in design.
